奔驰在纽约车展发了2017款C63敞篷版。该车的动力系统与硬顶版车型一样，是一台新的4.0升V8双涡轮引擎，标准版功率469马力，扭矩479磅-英尺（约合650牛米）。而C63 S功率为503马力，扭矩516磅-英尺（约合700牛米），搭配七速自动变速器。至于性能，C63 0-96公里/小时加速时间4.1秒，C63 S比它快0.1秒。C63最高时速经过电子限速为250公里，C63 S为300公里。在造型风格方面，新车除了采用电动软顶之外其他变化很小。该车配备18英寸钛灰色轮圈，C63 S配备19英寸轮圈。如果愿意多掏钱，还可选装20英寸哑光黑色合金轮圈。另外，C63配备的是后轮机械式限滑差速器，而C63 S配备的电控差速器。C63 S的变速器还增加了“赛道”模式，而C63只有“舒适”、“运动”和“运动强化”三种模式。此外C63 S配备了动态引擎支架，可根据不同的驾驶条件调整硬度以提升操控性和舒适性。2017款C63和C63 S将于今年秋季在美国上市。
2017 Mercedes-AMG C63 Cabriolet brings open-air V8 performance
Mercedes-AMG has staged the world premiere of the C63 Cabriolet on the dawn of the 2016 New York International Auto Show.
Echoing its fixed roof sibling, the range-topping model of the C Class Cabriolet lineup is set to bring open-top thrills thanks to the new familiar biturbo 4.0-liter V8 engine. As it’s the case with the other C63 models, the cabrio will be available with 469 hp & 479 lb-ft in the standard model and 503 hp & 516 lb-ft in the C63 S. Output will be delivered to the wheels exclusively through a seven-speed automatic transmission.
In terms of performance, the C63 Cabriolet will need just 4.1 seconds until 60 mph (96 kph) whereas the C63 S is going to be 0.1s quicker. The electronic top speed limiter will be programmed at 155 mph (250 kph) on the C63 and at 186 mph (300 kph) if you upgrade to the C63 S.
On the styling front, the changes compared to the coupe are on a subtle level, once we exclude the switch to an electrically retractable soft top. The C63 Cabriolet gets 18-inch wheels painted in titanium grey whereas the S has 19-inch rims featuring a similar look. Those willing to pay more can go for the larger 20-inch alloy wheel set finished in matte black.
Another difference between the two versions is the type of the rear-axle limited-slip differential which is mechanical on the C63 and electronic on the C63 S. The C63 S also gets a “RACE” mode for the transmission, whereas the C63 only has “Comfort”, “Sport”, and “Sport+.” In addition, the S has dynamic engine mounts that adapt their stiffness to the driving conditions as a move to improve handling and comfort.
Both the C63 and C63 S Cabriolets are programmed to hit US dealers this fall.
